Nearly 850,000 Mercedes diesels at risk of fire due to faulty valve

17/11/2021

Mercedes-Benz is recalling 848,517 vehicles from the C-Class, E-Class, G-Class and S-Class, as well as the CLS, GLC, GLE and GLS model series worldwide. Affected vehicles were manufactured between January 2017 and October 2021 and are equipped with a diesel engine.

The reason for the measure is an electrical switching valve. According to press reports, coolant can enter the vacuum circuit and come into contact with the affected valve. As a result, there is a risk of fire due to electrochemical reactions and rising component temperatures.

Do you know the year your car was made? You most probably don’t

The German Federal Motor Transport Authority (KBA) also confirms a fire hazard, although its recall database only mentions exhaust gas recirculation and not coolant in the vacuum circuit.

A software update is carried out in the workshop, and the faulty valve is also replaced. The internal code for this recall is “2090008“.

After reporting the vehicle's VIN code, you will find out if the defect is present on your car, or if it has already been resolved by the previous owner if the car was purchased second-hand.
